9 Claims.

My invention relates broadly to desk sets of the hydrostatic pressuretype and more particularly to an improved and simplifledconstruction ofdesk set.

One of the objects of my invention is to provide a construction of deskset embodying the principle of hydrostatic pressure in the feeding ofthe required ink supply and in which standard size bottles of inknationally distributed and 'assembled on the open market may be equippedwith a hydrostatic feed and readily mounted in position ,in a desk setfor supplying ink to a dip pen.

a simplified and inexpensive construction of hydrostatic pressure feedtype of desk set which includes an integrally molded receptacle and dippen guide with means for strapping an ink bottle in inverted position inthe receptacle for through thedip pen guide.

Still another objectof my invention is to provide a simplifiedconstruction of hydrostatic pressure operated desk set in which astandard size ink bottle may,be readily maintained in inverted positionin a receptacle by means of a strapping device yieldably engageable withopposite walls of the receptacle for controlling the feeding of ink to adip pen guide.

A further object of my invention is to provide a construction ofhydrostatic feed adapted to be engaged upon the neck of an ink bottleadapted to be supported in inverted'position in a hydrostatic desk setand operating to control the flow of ink supplied from the 'ink bottleto the desk 'set.

Other and further objects of my invention reside in the improved andsimplified construction of hydrostatic desk set, set forth more fully inFigure 1 is a perspective view of the improved desk set of my invention;Fig. 2 is a vertical longitudinal sectional view through one form ofdesk set embodying my invention; Fig. 3 is a vertical sectional viewtaken on line 3- 3 of Fig. 2 and line 33 of Fig. 4; Fig. 4 is ahorizontal transverse sectional view taken on linei-l of Fig. 2; Fig. 5is a horizontal transverse sectional view taken on line 5-5 of Fig. 2;Fig. 6 is a transverse sectional view of one construction of hydrostaticfeed cap taken on line 6- -6 of Fig. 7 which may be substituted upon'theneckof the ink bottle for, the usual closure cap; Fig. 7 is a plan Iview of the hydrostatic feed cap illustrated in Another object of myinvention is to providecontinuously feeding ink to a dip pen insertablethe specification hereinafter following by refer ence to theaccompanying drawings, in which:

My invention is directed to that class of hydrostatic desk setrepresented generally in my Pat- 20 ents Nos. 2,026,529, of January 7,1936, for Combined inkwell and bottle, and 2,112,907, of-April 5, 1938,for Desk set. In the arrangement of my present invention, I provide aconstruction of molded receptacle and dip pen guide which may beinexpensively manufactured on a quantityproduction basis. The portion ofthe desk set of my present invention that constitutes a .receptacle isprovided with supporting means arranged interiorly thereof, formingabutments against which an ink bottle equipped with a specialconstruction of hydrostatic feed may be mounted in inverted position.The receptacle is so designed that standard shapes and sizes of inkbottles may be readily mounted therein. It is only necessary to removethe usual closure cap from the standard ink bottle and substitute thespecial form of hydrostatic feed embodied in the structure of myinvention and mount the ink bottle in inverted position on the abutmentsprovided for that purpose 'interiorly of the receptacle'. In order tomaintain the ink 'bottle with relation to the receptacle, I provide aspring device which extends transversely of the ink bottle and yieldablyengages opposite sides of the receptacle .for maintaining the ink bottlein position. In the event'that the desk set may be lifted by graspingthe ink bottle, no injury results as the spring device maintains the inkbottle in position with respect to the receptacle. 60

The hydrostatic feed employed upon the ink bottle may be a foraminatedscrew cap,- an apertured stopper device, a cap having a centralprotuberance, a stopper device having a central protuberance, or a capand stopper device having tubular protuberances which are eccentric withrespect to the center of the cap or stopper device.

Referring to the drawings in detail, reference character I designatesthe molded base of the desk set having a projection 2 extendinglaterally therefrom. The molded base is interiorly apertured forreceiving a molded receptacle 3. The molded receptacle 3 includes avertically extending wall structure and an integrally formed dip penguide indicated generally at4. The dip pen guide has its axis formedsubstantially on an acute angle with respect to the vertical axis of thereceptacle 3. The dip pen guide has a hollow bore consisting of aninternal cylindrical portion 5, a frusto-conical dip pen guide portion6, a frusto-conical pen guide portion 1 and a cylindrical port 8extending between 'the interior of the receptacle 3 and thefrusto-conical portion I of the dip pen guide. A dip pen indicatedgenerally at 9 is adapted to be inserted through the dip pen guide whichincludes a peripheral flange l8 adapted to seat against thefrusto-conical portion 6 of the dip pen guide and a cylindrical portionll extending to the rounded annular bead l2 at the extremity ofcylindrical portion H. The penholder provides mounting means for the penfeed 14 which serves to secure the penpoint I5 in position. Thepenholder 9 when resting in the pen guide 5 in idle position has theflange [0 thereof in abutment with the frusto-conical portion 6 of thepen guide forming a dust-tight closure for the pen guide. When fullyinserted in the dip pen guide as represented in the drawings, Figs. 1,2,9 and 11, the penpoint I5 is submerged in the pool of i k l3 in the baseof receptacle 3.

The receptacle 3 is provided with a plurality of supporting abutmentsdisposed interiorly thereof, as indicated at I6, I I and I8. In additionto these abutments, there is an additional abutment l9 vwhich isbifurcated to form both a supporting abutment and an ink channel betweenthe port 8 in the dip pen guide and the bottom of the receptacle.

The supporting abutments IE, l1, l8 and I9 are arranged in diametricallyopposed relation and provide supporting means for an inverted ink'bottle equipped with the hydrostatic pressure feed means of myinvention.

In Figs. 1-8, I have shown an ink bottle 28 which is of the familiarrectangular shape nationally distributed and readily available in retailestablishments throughout the United States. The usual closure cap isremoved from a screw threaded neck 2| of bottle 20 and in lieu thereof,a foraminated cap 22 is screwed over the screw threads 2| of the cap.The foraminated cap 22 is apertured at 23 for permitting the controlledsupply of ink from the ink bottle to the pool 13 in the base ofreceptacle 3. The receptacle 3 is provided with lugs 24 which are moldedintegrally with the upper portion of the wall of receptacle 3 withgrooves 25 formed in lugs 24. A spring device 26 in the form of a bandhaving substantially'hook shapedyieldable ends 21 is arranged to besprung over the ink bottle 20 so that the flat intermediate portion ofspring 26 tends to continuously place the ink bottle in invertedposition against the supporting abutments I6, [1, l8 and I9. The hookshaped resilient ends 21 engage through the grooves 25 under the lugs24, thereby maintaining the ink bottle 28 rigidly in position. Eventhough the ink bottle 20 should be grasped by the fingers and the deskset thus raised, the spring 26 maintains substantially locked engagementwith lugs 24 so that the desk set including the ink bottle is raised asa unit without danger of spilling the ink. As shown in Fig. 8, thehydrostatic feed of the ink may be readily started by tilting the deskset at a slight angle.

In Figs. 9 and 10, I have illustrated the desk set of my invention asembodying an ink bottle of the cylindrical type. The cylindrical bottleis indicated generally at 28 having a screw threaded neck 29 from whichthe customary closure cap is removed and into which a substantially flatstopper 38 is inserted. The substantially flat stopper 38 is aperturedat 3| for the hydrostatic feed of ink from the ink bottle 28 to the poolI3 in receptacle 3. The stopper 3!] has the annular peripheral edgethereof provided with resilient soft material 32 which yieldably engagesthe interior annular wall of the neck of bottle 28, thereby establishinga leak-proof joint between the stopper and the ink bottle.

In Fig. 11 I have illustrated a modified form of hydrostatic feed asapplied to the threaded neck 29 of ink bottle 28. The hydrostatic feedin this form of my invention includes a screw threaded member 33engageable with screw threads 29 with a central tubular protuberance 34depending therefrom. The central protuberance 34 is apertured in oneside at 35. Protuberance 36 is cut-off at an angle represented at 36 sothat the shortest longitudinal dimension of protuberance 34 issubstantially opposite aperture 35.

In Fig. 12, I have shown another modified form of hydrostatic feed inwhich stopper 3], provided with annular packing ring 38 of relativelysoft material, is mounted interiorly of the neck 28 of bottle 28. Thestopper 3'! has a central tubular protuberance 39 thereon. Theprotuberance 39 is cut off at an angle indicated at 4|. An aperture 40is provided in the protuberance 39 along the longest longitudinaldimension of protuberance 39.

In order that a fresh supply of ink may be delivered immediatelyadjacent the point l5 of the dip pen, I may employ a modified form ofhydrostatic feed as represented in Fig. 13 wherein screw member 33a hastubular protuberance 34a extending therefrom in a position eccentric tothe center of the cap. By this arrangement the bottle 28 may beangularly shifted to bring the tubular protuberance in close proximityto the point 8 of the dip pen. The end of protuberance 34a is shaped asindicated at 36a and the protuberance is apertured at 35a to insurehydrostatic feed of a new supply of ink immediately adjacent the end ofthe dip pen.

As indicated in Fig. 14, a stopper 31a secured in position by yieldableperipheral edge portion 38a may be provided with a tubular protuberance39a which is eccentric with respect to the center of the stopper 31a.Tubular protuberance 39a is provided with an aperture 48a and anangularly cut-off end portion Ma. The fact that the tubular protuberanceis eccentric with respect to the center of the cap 31a allows the inkbottle to be shifted to such position as will insure a fresh supply ofink at all times to the end of the din pen. 4

Venting of the desk set to facilitate the hydrostatic feeding of the inksupply is accomplished by virtue of the space existing between the sidewalls of the inverted ink bottle and the interior walls of thereceptacle 3, whereby atmospheric pressure is maintained with respect tothe surface bore of the pen guide 4 coincident with the plane of theforaminated cap 22 in the form of my invention illustrated in'Figs.1-8,or the plane of the insert shown in Figs. 9-10, or the upper limitof aperture 35, 40, a-or a in the forms of my invention shown in Figs.11,?12, 13 and 14, respectively. As heretofore noted, the hydrostaticfeeding of the ink may be started by tipping the desk set as indicatedgenerally in Fig. 8.
